I’m not sure what else to do or where to look, any help would be greatly appreciated. my 289 has had the following done: Rebuilt and cleaned the Carb, inside and out. Dropped the tank, acid bath cleaned and sealed Cleaned and restored the sending unit All new gas line filters (twice) for a tot…

If you have the original air cleaner assembly, put it back on and you will get warm air into the carburetor. Make sure the hot air tube is connected unless you have a steel pipe attached to the exhaust manifold choke stove. It may not help with your problem if the engine stalls in neutral. In that c…

You might check those distributors out Keith. Some early emission models had a retarding diaphram added to the normal advance diaphram but no distributor that I am aware of was designed to operate such that the timing was retarded when the engine was accelerated. And I am quite familiar with domesti…

“but no distributor that I am aware of was designed to operate such that the timing was retarded when the engine was accelerated.” MOST vacuum systems were designed this way as most use manifold vacuum…Some used “ported vacuum”, taken from a carburetor port that only delivered vacuum at part-thrott…

" but no distributor that I am aware of was designed to operate such that the timing was retarded when the engine was accelerated." There were a few systems that had dual diaphragms, but in most pre-emissions systems, vacuum was used to advance the timing. Under acceleration, there is less vacuum,…

cont. I said that the vacuum advance retards the timing, that was a poor selection of words on my part. The vacuum advance does not retard the timing, but under acceleration, there is less vacuum advance. Under full acceleration at low RPM, there is NO vacuum advance, only mechanical.

Back in '67 there was virtually no emission controls. Things started to be added to the '68 models and by the early 70’s there were air pumps, tubes, and vacuum lines galore in most engines. But in a '67 289 V8 you pulled and plugged the vacuum line to set the timing once you had the dwell of the …

Maybe I am confused here. Does the engine bog down or does it stall and die when the throttle is quickly opened? And if the throttle is opened slowly can the engine rev to 2,000+ rpm?

When you goosed the engine, that was the centrifugal advance moving the timing…usually about 20-25 degrees…When you hooked up the vacuum line, it would jump another 20-25 degrees. 40-50 degrees total advance was fairly standard…Holding the RPM at around 2200, you could observe the total advance with…

Uncle Turbo, I did the same thing to many cars of that era. With the line off and plugged, most cars called for 4 to 8 degrees of advance at idle. With the line hooked up, at idle with a manifold vacuum of about 20", the timing mark would move another 7-8 degrees advance. When you first opened t…
